Abstract

A level control device of a vehicle may include an angle-of-rotation sensor for measuring the distance between a vehicle chassis and a vehicle axle or wheel according to an inductive principle. The sensor may include an electrical coil that has a coil core for generating a magnetic field, and at least one eccentric body capable of swiveling about an axis of rotation as a function of the distance. The coil core may be disposed in a stationary manner relative to the coil the eccentric body may be made of a ferromagnetic material and captured at least partially by the lines of force of the magnetic field of the coil in such a way that, solely by a change of its position relative to the coil core, a change of the inductivity of the coil is brought about as a measure for a change of the distance.
